can you always see the eggs rocking???

I was just wondering can you always see soon to hatch eggs rocking or wiggling? My first hatch I thought it was my eyes playing tricks on me but sure enough they were rocking. This time I around I swore I could see them rocking again but I'm only on day 16 I think it was the day before or so when I saw them rocking before? Can u always see them rocking and on what day does this usally start being able to see them rocking? Are my eyes just playing tricks on me this time and I am so wanting to see them rocking but they really arent??LOL

Quote:Yeah im thinking it was a day before or so when I saw my first hatch start rocking. I think my eyes are playing tricks on me..LOL Because I think I set for 15 mins today just staring at eggs and NOTHING but I swore the other day I could see them rocking..LOL wow!

I've always seen my eggs rocking and wiggling when i take them off the turners on day 18 i see them rocking and wiggling almost as soon as i take them off.... and they would continue to rock and wiggle till day 20 when i would always get my first pip and they rock and wiggle while they hatch to ... i always here mine peep before they pip though... Although this time i'm doing the egg carton method so i wont be able to see my chicken eggs rock or wiggle this time
